Answer:
Newton's first law states that when the vector sum of all forces acting on an object (the net force) is zero, the object is in equilibrium. If the object is initially at rest, it remains at rest. If it is initially in motion, it continues to move with constant velocity.
Explanation:
In my own words, I would say that physics is an area of science that seeks to explain and understand the fundamental nature of the dynamics of objects, essentially defining how objects can interact, in space and in time.
Momentum = (mass) x (speed)
If the speed is zero, then the momentum is zero.
<span> the tangent function of 2mi/5mi = 21.8 degrees
cosine of that angle = cos (21.8 degrees)
=0.928
multiply 0.928 with 570 = 570*0.928
Closing velocity = 529.23 mph
</span><span>As the plane gets closer to radar station, tangent function becomes infinity and the cosine function becomes zero.....
</span>0*570 = 0
Answer:
15 nC and 10 nC
Explanation:
qA + qB = 25 nC = 25 x 10^-9 C
F = 5.4 x 10^-4 N
d = 5 cm = 0.05 m
Use the Coulomb's law

By substituting the values, we get

qA x qB = 1.5 x 10^-16 C
So, 



qA = 15nC or 10nC
So, qB = 10 nC or 15 nC
